         The  d.m  Tcl/Tk  GIS  manager  GUI  has  been  replaced  by gis.m.  The d.m code is now
       UNMAINTAINED and OBSOLETE and left here as a courtesy to legacy users. The  gis.m  GUI  is
       soon to be replaced by a new wxPython based GUI.

       The  GRASS  GIS  Manager provides an interactive graphical interface to GRASS commands. By
       default, it is started automatically with each GRASS session. The GIS Manager can be  quit
       by  selecting the 'File->Exit ' menu item. The GIS Manager can be restarted from the GRASS
       command line shell by typing "d.m &".
       The GIS Manager includes a set of pull-down menus for many GIS functions  (analysis,  file
       I/O,  GIS  configuration  and  management),  two  rows  of  buttons  that  control display
       functions, an upper window in which layers to display are  organized,  a  row  of  display
       monitor  control  buttons along the left side of the layer tree window, and a lower window
       which contains options panels for layers in the layer tree.
       The top row of buttons control a series of display functions: displaying  or  redisplaying
       all  map  layers  in  the  default  monitor  window,  zooming and panning, simple queries,
       starting  NVIZ  (n-dimensional  visualization)  or  XGANIM  (display   animator)   display
       interfaces, and saving or opening group display file. The second row of buttons add, copy,
       or remove map layers to be displayed,  and  activate  the  raster  and  vector  digitizing
       interfaces. Mouse-over help is available for all buttons.
       Map  layers  are  organized  as  a layer tree, in the window below the buttons. Layers can
       include raster and vector maps, text, map enhancements (scale and north arrow, grids,  and
       frames),  and  commands  (where any GRASS command be written). Layers are displayed in the
       order added to the layer tree: the first added (i.e., at the top of the tree) is displayed
       first,  followed  by  the  next added, etc. This means that the uppermost layer is 'on the
       bottom' and the lowermost is 'on top' if layers are thought of  as  a  series  of  stacked
       overlays. Any layer can be renamed by double clicking on its name and typing a new name.
       The  check  box  to the left of each layer makes it active for display.  Active layers are
       only displayed/redisplayed when the display button is pressed.  Layers  can  be  organized
       into  groups;  entire  groups  can  be activated or deactivated for display. Groups can be
       saved to a file and opened in subsequent sessions, restoring all layers and their  display
       When  a  layer  is  selected  with the mouse, its options are shown in the panel below the
       layer tree window. Help for each layer type can be accessed by pressing the  GRASS  button
       in the option panel.
       The  monitor  buttons  along  the  left  side  of the layer tree window open or select (if
       already open) one of seven display monitors (named x0-x6). Layers are be displayed in  the
       currently  selected  monitor.  If  no  monitor  is  open  and selected, map layers will be
       displayed in monitor x0.


   Display active layers (current region)
       Displays all active layers at current resolution and region extents.  Monitor x0  will  be
       started automatically if a monitor is not already open and selected.

   Display active layers (default region)
       Resets  the  region to the default resolution and extents, and displays all active layers.
       See g.region -d.

   Display active layers (saved region)
       Opens a dialog to select a saved region setting. Resets the region to the  resolution  and
       extents of the selected saved region, and displays all active layers. See g.region.

   Erase to white
       Erases  the currently selected monitor to a white background; also removes all frames. See
       d.frame -e.

       Starts the NVIZ, n-dimensional visualization module and interactive  graphical  interface.
       See .

   Fly through path for NVIZ
       Starts  a  GRASS  module  for interactive creation of a fly-through path to be animated in
       NVIZ. See d.nviz.

   Animate raster map series
       Starts the XGANIM interactive  interface  to  display  a  series  of  raster  maps  as  an
       animation. See .

       Interactive  zooming  with  the  mouse  in the active display monitor.  Zooming resets the
       region extents (both size and location of area displayed). A set of prompts for using  the
       mouse for zooming will appear in a separate x-terminal. A simple (i.e., non-draped) raster
       map or vector map must be active and displayed in  the  current  monitor.  If  no  map  is
       currently active and displayed, a dialog will appear in which a map can be chosen. See

   Return to previous zoom
       Resets the region to the layer extents in effect prior to zooming.

   Pan and recenter
       Interactive  selection  of  a  new  center  of view in the active display monitor. Panning
       changes the location of the region extents but not the size  of  the  area  displayed.   A
       simple  (i.e.,  non-draped)  raster  map or vector map must be active and displayed in the
       current monitor for panning to function. See d.zoom -p.

   Query map (select map first)
       Query selected raster (only the base map of a draped map will be queried), RGB raster  map
       (all  three  map channels will be queried), or vector map using the mouse. A map has to be
       selected before query.  Vector charts and thematic vector  maps  cannot  be  queried.  The
       results  of  a  raster  map query will be displayed in a new x-terminal.  Depending on the
       setting in the vector panel, the results of a  vector  map  query  will  be  displayed  in
       graphical form window or in a new x-terminal.
       The default display mode for vector map queries can also be set with the GRASS environment
       variable DM_FORM_MODE.
       g.gisenv set=DM_FORM_MODE=txt for displaying vector query results in an x-terminal
       g.gisenv set=DM_FORM_MODE=gui for displaying vector query  results  in  a  graphical  form
       See d.what.vect.

   Measure lengths and areas
       Interactive  measurement  of  lengths  and/or areas defined with the mouse.  An x-terminal
       will open with prompts for using the mouse to measure lengths and areas, and  display  the
       results  of  measurement.  Lengths are measured in meters; areas are measured in hectares,
       square miles, and square meters. A display monitor must be open and selected,  but  it  is
       not  necessary  to  select  or  display  a  map in order to measure lengths and areas. See

   Geographical position
       Interactive identification of geographical  position  in  the  coordinate  system  of  the
       current location. An x-terminal will open with prompts for using the mouse and display the
       xy coordinates of at each mouse click location. See d.where.

   Erase all layers and create a new group
       Removes all layers in the layer tree and creates a new, empty group to  which  new  layers
       can be added.

   Open an existing group file
       Opens  an previously saved group file, containing a set of display layers and their option

   Save layers to group file
       Saves current set of layers and their options to a group file.

   Print map
       Uses to print simple raster, vector, and text layers.  Currently  supported  output
       formats are Postscript, PDF and PNG. See


   Add raster layer
       Adds a raster map to the layer tree. Raster display options include: displaying a selected
       subset of raster cells, defined by their cat values;  draping (or "fusing") a  second  map
       over  the base map; and displaying legends for the base map and draped map. See d.his (for

   Add RGB or HIS raster layer
       Combines and displays three raster maps defined as  red,  green,  and  blue  channels;  or
       combines and displays two or three raster maps defined as hue, intensity, and (optionally)
       saturation channels. See .

   Add raster legend
       Adds a legend for a single raster map to the layer tree. Multiple options  for  formatting
       the legend are available. See d.legend.

   Add vector layer
       Adds  a  vector  map  to  the  layer  tree.  A  large  number of options are available for
       displaying the vector map, including: outline and fill  color,  icon  type  and  size  for
       points,  line  widths  for all vector types, automatic labeling using an attribute column,
       querying cats or attributes to limit vectors displayed,  and  restricting  vector  display
       depending on region size. See d.vect.

   Add thematic charts layer (for vector points)
       Adds  layer  in  which  pie  or  bar  charts  can be automatically created at vector point
       locations. Charts display values from selected columns in the associated attribute  table.
       Options  include:  chart type, layer and attributes to chart, chart colors, and chart size
       (fixed or based on attribute column). See d.vect.chart.

   Add thematic map layer (for all vector types)
       Adds layer for thematic display values from a numeric attribute column associated  with  a
       vector  map.  Options  include:  thematic  display type (graduated colors or point sizes),
       methods for creating display intervals, SQL query of  attribute  column  to  limit  vector
       objects  to  display,  control  of  point  icon types and sizes, control of thematic color
       schemes, creation of legend for thematic map, and saving the results of  thematic  mapping
       to a instructions file for later printing. See d.vect.thematic.

   Add vector labels layer (from existing labels file)
       Add  text  layer  from  a  labels  file  for  vector  objects created with v.label command
       (accessed from the "vector->develop map->create text label file for vector features"  menu
       item). A labels file can also be created with a text editor.  See d.labels.

   Add freetype text layer
       Adds  layer  to  display  a  line  of  freetype  text.  Options include: text placement by
       coordinates (geographic or screen) or mouse; text alignment and rotation,  font  and  line
       spacing; and text size, bolding, and color. See d.text.freetype.

   Add text layer
       Adds layer to display a line of text using default GRASS font (selected with d.text.

   Add scalebar and north arrow layer
       Adds  layer  to  display  a  combined  scalebar  and north arrow. Options include scalebar
       placement (using screen coordinates or a mouse), scalebar format, and scalebar colors. See

   Overlay grids and lines
       Adds  layer  to  display regular grid (for all locations), or geodesic and rhumblines (for
       latitude/longitude locations only). Grid options include: grid  and  border  colors,  grid
       origin, and grid line spacing.  Geodesic and rhumbline options include: line color, and xy
       coordinates (geographic) of line endpoints. See d.rhumbline.

   Create or select display frames
       Adds a layer to define (or  select  predefined)  display  frame.  A  display  frame  is  a
       rectangular  subarea  of a display monitor, within which maps can be displayed. All layers
       following a frame  layer  will  be  displayed  within  the  frame  defined  in  the  frame
       layer—until a new frame layer is added and new frame defined/selected. This allows a
       single monitor window to be subdivided into multiple frames, each  of  which  can  display
       different  maps,  legends,  scalebars  and north arrows, or other layers. For example, the
       monitor could display a detail map and a small frame  could  display  an  inset  map.  See

   Add command layer
       Adds  a  layer  defined by a GRASS GIS command or command list. For a command list use the
       pipe symbol as "|" as separator.

       E.g.:  d.rast soils | d.rast -o roads | d.vect streams col=blue

   Add group
       Adds an empty layer group. Layers can then be added to the group.

   Duplicate selected layer or group
       Adds a new layer that duplicates the selected layer.

   Cut selected layer or group
       Deletes the selected group or layer.

   Digitize raster or vector maps
       Starts the raster digitizing or vector digitizing module, depending on whether a raster or
       vector map is selected. Raster digitizing always creates a new map. Vector digitizing will
       either edit an existing map (if an existing vector map is selected in the layer  tree)  or
       create  a  new  vector  map (if the name of the new vector to be created is entered in the
       'vector name' field of the options panel for a vector map layer). See v.digit.
